Quality Characteristics of Mugwort-Tofu with Various Salts

다양한 염을 첨가한 쑥두부의 품질 특성

  • Published : 2008.10.31

Abstract

This study was conducted to evaluate the quality characteristics of mugwort-tofu prepared by purified salt (A1), sun-dried salt (A2), bamboo salt (A3), and deep ground water salt (A4) in addition to $CaCl_2$ as coagulants. Addition of various salts with $CaCl_2$ increased yield of the tofu resulting in high content of lipid, protein and mineral contents of mugwort-tofu. Sun-dried salt was most effective in yield of the tofu among tested salts. It was also most efficient in increasing protein, and lipid contents of the tofu. The amounts of Ca, K, Mg, and Na were highest in mugwort-tofu prepared with sun-dried salt, while they were lowest in the tofu with deep ground water salt. The texture analysis showed the tofu prepared with various salts generally increased the hardness and gumminess of the tofu significantly. The sensory evaluation of the tofu with various salts demonstrated that the saltiness, tastiness, chewiness, and overall acceptance were enhanced significantly. Among tested salts, bamboo salt showed the highest overall acceptance in mugwort-tofu, followed by deep ground water salt, purified salt, and sun-dried salt.

두부 제조 시 응고제로 $CaCl_2$을 사용하고, 두부에 간을 배게 하여 두부의 맛에 대한 품질향상을 목적으로 정제염, 천일염, 죽염, 심층해염을 첨가한 실험군 쑥두부와 염을 첨가하지 않은 대조군 쑥두부의 수율, 일반성분, 조직감 측정 및 관능검사를 실시하였다. 천일염, 죽염, 심층해염을 첨가한 쑥두부의 수율은 $202.29%{\sim}207.50%$로 염을 첨가하지 않은 대조군의 수율 185.1%에 비하여 통계적으로 유의하게(p<0.001) 높았다. 그리고 조지방, 조단백질, 조회분의 함량은 다양한 염을 첨가한 실험군 쑥두부가 염을 첨가하지 않은 대조군에 비하여 통계적으로 유의하게(p<0.001) 높게 나타났다. 조직감 측정에서는 hardness와 gumminess에서 실험군 쑥두부가 대조군 쑥두부보다 유의적으로(p<0.05) 높은 값을 보였지만 brittleness와 cohesiveness, chewiness에선 유의적인 차이점을 찾지 못하였다. 관능검사 결과는 경도와 탄력성에선 유의적인 차이점이 없었지만 짠맛, 구수한 맛, 씹힘성, 전체적 기호도에선 대조군 쑥두부보다 염을 첨가한 실험군 쑥두부가 통계적으로 유의하게(p<0.001) 높은 점수를 받았으며, 특히 죽염 쑥두부와 심층해염 쑥두부에서 두부 맛에 영향을 미치는 구수한 맛과 전체적 기호도에서 높은 점수를 받았다.
